      Here’s an article from the July 2013 Antique Outboarder on EXTERNAL rotary valve motors that you might find interesting (and a photograph of Lou Fageol contributed by me :D).

        The plunger is most likely to prime the motor, beyond that you need to post pics 🙄

        quote Jerry:

        I recently picked up a motor with the sheave showing "OUTBOARD MOTOR CORPORATION"..It has a funky looking carburetor with some sort of plunger on top and a shroud where the Venturi should be….I was told it was a 1933 model.
        Can someone tell me if the rotary valve motors are better runners than reed type? What is the advantage? It appears to be about 3 or 4 horse.I have no idea how to prime it since I can’t see the Venturi to inject fuel for testing…Jerry
